KIT'CHEN-VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 273,216, dated February27, 1883. Application filed November 22, 1882. (No mndel.i

ment in Kitchen-Ventilators, of which the following is a specification.

My present invention is intended to be used in connection with uiyimproved house-cooling device, described in the application for a Patentof the United States filed August 9, 1882, Serial No. 68,868, and hasfor its object to prevent the smell caused by cooking animal andvegetable substances from being perceptible in any portion ofthebuilding, whether in the basement or the floors above, by providingsuitable means for causing the fumes or vapors generated by the cookingin the kitchen to he carried out by the partial vacuum caused by thedraft in the smoke-flue, and discharged with the smoke at a higherelevation than the roof of the building.

In the accompanying drawings, Figure l represents apartial sectionalelevation ofthe basement and irst ioor of a house, showing my aforesaidhouse-cooling device with my present improvement applied thereto, therange and the chimney-breast above the lire being partly broken out toshow the interior. Fig. 2 is a detail section (drawn to a larger scalethan in Fig. l) of the device, whereby the fumes from the cooking aredrawn into and discharged through the smoke-flue, and which deviceconstitutes the main feature ofmy invention. Fig. 3 is a cross-sectionof the same, taken through the line a' x of Fig. 2. Figs. 4, 5, and 6represent sections similar to Fig. 2 of modifications of theconstruction shown in said figure. Fig. 7 is a detail vertical sectionthrough the line y y of Fig. l, showing the ordinary smellcatcher andregister in front of the chimneybreast above the range.

Like letters of reference indicate like parts in the several ligures.

A is the chimney-breast, and a the ordinary due in the same leading fromthe kitchenrange.

B is the discharge-pipe leading from the stove or range, and is providedwith a damper, b, by which the heat is prevented from ascend- Amay bedone in ing through the iiue c, when so desired, and let through theauxiliary smoke-tine C, which is provided with a damper, o, and runs outlfrom the pipe BV laterally through the wall of the chimney-breast andthence to and through the rear wall ofthe building, outside of whichlatter it is turned upward, ascending vertically above the roof of thebuilding, as described in my application previously referred to. Inorder, now, to utilize the draft created by the gases ascending throughthe flue C, for removing the gases generated by cooking, and thus toprevent the annoyance in the building of the smell produced by suchgases, I have made the following simple construction:

The pipe D, which, as 'in my previous application, is also used toprevent radiation of heat from the pipe C into the kitchen, I extendthrough to the interior of the side wall of the breast A, leaving itsinner end open, so that all the gases from the cooking, and which haveentered into the iue a, will have an opportunity to enter the pipe D.

At the outer end of the pipe D, I provide one or more holes or passages,connecting it with the interior of the smoke-fine C. This several ways,as illustrated in Figs. 2 to 6, the operation of all of which will beplainly understood with reference to Fig. l, the smoke and heated airfrom the fire entering and ascending through the flue C in the directionas indicated by arrows l, and the gases from cooking animal andvegetable substances being drawn by the draft of the smoke-flue into theannular space between the pipes C and-D, and thence through theaforesaid passages from the pipe D directlyinto the smokeflue, fromwhich they then escape above the roof of the building, together with thegases from the fire, their course being indicated by the arrows 2. Thevapors from the cooking enter the iiue ct through an opening, O, madethrough the chimney-breast above the range, the said opening beingprovided with an ordinary smell-catcher,77 consisting oa shed,E, and aregister, e, as shown in Fig. 7, the course of the vapors being thereindicated by the arrows 3.

The openings or pipe D with the pipe IOO letter d. Said passages may beformed by simply perforating the pipe C, as shown in Fig. 4, or bymaking the end of the horizon tal part ofthe Hue C suciently smallerthan the elbowjoint to leave a space between the said pipe and thesurrounding elbow, as shown in Fig. 5; or a separate small pipe may beinade t0 connect the exterior of the pipe D with the interior of thepipe C in the manner shown in Fig. 6; butI prefer the construction shownin Figs. 2 and 3. In this one or more openings, (but preferably four,arranged as in Fig. 3,) are made by cutting or slitting through the pipeC three sides of a square or other iigure, leaving one side uncut, andthen bending inwardly the lip m thus formed. In order that no eddy mayform in the current and interfere with the vacuum, I then bend a pieceot iron or tin-plate to the shape of the outline ot' the saidinwardly-projecting lip m, in order to form n channel, n, and solder itsedges to the said lip and to the inner side ot' the pipe C in thedirection of the current.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 1. The combination of the opening O, the smoke-flue BC, and a pipe, D, opening with its inner end into the chiinneybreastflue and with its outer end into the said smoke-pipe, substantially asand for the purpose set forth.

2. The combination ofl the opening 0, the smoke-flue B (l, the pipe D,opening into the chimney-breast flue and forming an annular space aroundthe said smoke-flue, and passages connecting the said exterior pipe withthe said smokeflue, substantially as and for the purpose set forth.

3. The combination ofthesmoke-tlueB (land the pipe D, open at its innerend in the chimney-breast flue and forming an annular space around thesaid smoke-line, the interior pipe, C, being perforated at or near theouter end ot' the exterior pipe, D, substantially as and for the purposeherein set forth.

4. The combination of' the smoke-line B C and the pipe D, open at itsinner end'in the chimney-breast flue and forming an annular space aroundthe said smoke-flue, channels d being formed at the outer end ot' thepipe D, upon the inside of the pipe C, by the cut and inward-bent lip mand the channel plate a, substantially as and for .the purpose hereinset forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence ot' two witnesses.
